Abstract
In a computing system utilizing redundant storage devices arranged in the RAID disk array, data is stored in the computing system using a memory cache created from system memory and the disk array. A checkpoint module detects a fault in the computing system and generates a fault indication, and a cache manager writes data and parity to the memory cache in a first mode, and writes data and parity to the storage device in a second mode. In response to the fault indication, the checkpoint module copies the data contained in the cache to the disk array, and switches the cache manager from the first mode to the second mode.
